Which toxin is produced by Karenia brevis that causes neurotoxic shellfish poisoning?

Explanation:
Brevetoxins are the toxins produced by Karenia brevis that cause neurotoxic shellfish poisoning. Karenia brevis, responsible for red tides, makes brevetoxins which accumulate in shellfish that filter-feed in the affected waters. When people consume contaminated shellfish, the brevetoxins affect nerve cells, leading to symptoms like perioral tingling, numbness, dizziness, and sometimes breathing difficulties. These toxins are heat-stable, so cooking does not destroy them, making avoidance during red tides crucial. Other toxins listed come from different sources and cause different syndromes: saxitoxin is linked to paralytic shellfish poisoning, domoic acid to amnesic shellfish poisoning, and tetrodotoxin is a potent toxin associated with pufferfish, not Karenia brevis.
